TOY.

Application filed April 15, 1915.

To all whom it may concern:

Be it known that I, EDWARD S. SAVAGE, of the city of Rochester, State of New York, have invented certain new and useful Improvements in Toys, of which the following is a specification.

Certain broader features of this invention for which I now solicit a patent are set forth in my prior application Serial No. 879,128 filed December 26, 19141 of which this application is a continuation. Figures 1 and 2 herein having been copied from that case. Some after appended claims will be found generic to the species illustrated in Figs. 1 and 2 and others to Figs. 2, 4: and 5. In my earlier application I have disclosed and claimed the broad invention of a method of and means for controlling motion in me chanical toys whereby the motion is controlled within the toy itself and a steady comparatively slow action or application of the motive is secured without the use of the usual complex and more expensive train of gears and other devices.

This application is confined to a particular embodiment of the broad invention wherein my objects are to produce a slow and steady rotary motion and toassemble the actuating spring the retarding means and the moving part in a most self contained and compact form; and my invention con sists in the novel construction shown in the accompanying drawings, in which- Fig. 1 isavertical section taken longitudi nally and Fig. 2 is a vertical section taken transversely, of one form of the invention. Fig. 3 is a vertical section taken transversely of a modified form of the invention and Fig. 4 is a vertical longitudinal section and Fig. 5 is a plan partly in section of another application of the invention.

Referring by numerals to the accompanying drawings, 1 is the body portion which may be made to represent a living creature, a moving vehicle or any animate object which may be simulated in a mechanical toy.

In Fig. 1 and Fig. 2 the body is a sheet metal stamping in the form of a bug. The body is supported alittle forward of its center of gravity by the shaft 2 about which the cylinder 3 revolves. The cylinder 3 is closed at both ends by the caps 4: having center holes which serve as bearings. A wooden roller which acts as a tractor is fitted tightly to the cylinder 3. A friction piece 6 fits tightly on the shaft 2 and has two arms 7 Specification of Letters Patent.

which extend parallel to the shaft and close to but notin contact with the inner surface of the cyhnder. The coiled spring 8 is attached at one end to the shaft or to the friction piece and at the other end to the cylinder or cylinder cap. The space within the cylinder surrounding the shaft, spring and motion piece, is filled or partly filled with a vlscous material such as soft pitch or thick molasses. This viscous material sticks to the inner surface of the cylinder 3 and to the arms of the friction piece causing a resistance which effectually prevents rapid revolution of the cylinder and its roller 5 but permits the cylinder to turn slowly until the spring is completely unwound. The spring is wound by holding the top in the hand and drawing it backward while pressing the roller against some surface such as a table or floor. In action the rotation of the roller draws the toy forward slowly unt1l the spring is unwound. Obviously the speed of motion depends upon the strength of the spring and the nature of the viscous substance employed.

In Fig. 3 the body is a sheet metal sta1nping in the form of a bug having the same shape as that shown in Fig. 1 and Fig. 2. This form is similar to the one described above except that the shaft 2 revolves and carries the tractor rollers 5 while the cylinder 3 is fixed being attached to the body portion by means of the supports 10.

Fig. 1 and Fig. 5 show another application of my invention with certain new features, in which the body 1 is a sheet metal stamping in imitation of a turtle and is carried by the lower shell 11 which also carries the leg members 12 and 13 which are pivoted at 141 and 15 respectively. The shell 11 is supported a little ahead of its center of gravity by the shaft 2 which is fixedly connected to the shell at the ends of the shaft. The cylinder 3 is closed at both ends by the caps 1- having center holes which serve as hearings on which the cylinder revolves. A tractor roller 5 attached to the cylinder is formed of two drawn sheet metal shells identical in shape with curved lateral edges. The shells are placed face to face with a uniform space between forming a pcripheral double track cam 16. The spring 8 is coiled about the shaft 2 being attached at one end to the shaft and at the other end to the cylinder 3. Arms 17 and 18 are carried by the leg members and cooperate with.

a the cam 16, so that rotation'of the roller will cause oscillation of the leg members. i The space within the cylinder 3 is filled with v a viscous material and the function of the I frict on piece described in connection wlth' V Fig. land Flg. 2 is performed in this case bytheoifset portion of the curved shaft 2.

s not perhaps technically viscous which would Ilprefer to use a truly Vviscous "material such as those mentioned above, but it 1s ob vious that there are equivalent materials give substantially the same results, the func tion of this element being to cling to or yield slowly before the action of the part to be retarded.
